Origin: This town was one of the first granted by Governor Benning Wentworth. When the New Hampshire-Massachusetts border was established in 1741, territory that was in Amesbury and Salisbury, Massachusetts, became part of New Hampshire. South Hampton was chartered in 1742 from that territory. Much of the area was already settled when the boundary line was changed, and some residents petitioned to become part of a town closer to them. The east end was annexed to Hampton Falls in 1742 and the west side was separated to form Newton in 1748. At one time, the town was home to over twelve different religious sects.
